	Primary Examiner--Neil McCarthy Attorney, Agent, or Firm--Standley & Gilcrest [57] ABSTRACT The present invention has two basic aspects: (a) a mechani- cal method for controlling the macrofouling of zebra mus- sels; and (b) a mechanical apparatus for reducing the dis- solved oxygen of natural source water, such as industrial or municipal use, to a level below that sufficient to support the survival respiration of zebra mussels. 4 Claims, 3 Drawing Sheets
